A wireless network allows computers equipped with wireless adaptors to connect to the network wirelessly. However, the wireless signal only travels for a limited distance, therefore limiting the coverage area of the network. To correct this problem, you can use a wireless range extender. The range extender picks up the current wireless signal, then broadcasts it beyond the range of the network's wireless router. To set up the Wi-Fi range extender, you will need the current wireless network's name and pass key.
Plug one end of the power cord into a wall socket and the other end into the Wi-Fi range extender.
Connect one end of an Ethernet cable into the Internet port at the back of the range extender and the other end into the Internet port on your wireless router.
Insert one end of another Ethernet cable into the LAN port on the range extender and the other end into an open Ethernet port on any computer that is connected to the network.
Launch a Web browser, then type the IP address of the Wi-Fi extender into the address field. An example of a common IP address is 192.168.3.1. Refer to the user manual for the exact address of the range extender. The extender's login window will open.
Type the login information into the open boxes. Check the user manual for the specific login information for your wireless extender. The extender's configuration page will open.
Click the "Wireless Settings" or "Wireless" tab, then enter the network's wireless name in the "SSID" box. Click "Save" or "Apply." Click "Wireless Security" or "Security." Select the wireless network's security type such as WEP and type the security key in the "Password" or "Security key" box, then click "Save."
Unplug the Ethernet cords connecting the range extender from the computer and the router. Position the extender within the range of the current wireless network.
